How Sesame Street Brings Muppets to Life

"Sesame Street" premiered in 1969. Since then, it has grown into a worldwide franchise with more than 4,000 episodes. "Sesame Street" has won more than 100 awards, including eight Grammys, four Parents' Choice Awards, and 71 Emmys -- more than any other show in history. It has been host to more than 250 celebrity guests and has been watched by 77 percent of all preschool-age kids.

"Sesame Street" was the brainchild of a young television documentary producer named Joan Ganz Cooney. The concept of the show's format was inspired by TV commercials, which Cooney thought would hold young viewers' attention better than traditional children's programming. She had noted that kids responded to "banana-peel humor." From these observations, the most successful children's show in the history of television was born.

The use of puppets had been envisioned for "Sesame Street" from the beginning. It was felt that Muppets were the perfect means to entertain preschoolers while they learned. In the mid-1960s, Jim Henson was already a renowned artist and puppeteer and was brought in to create a family of puppet characters for "Sesame Street." The late Henson also came up with their unique name -- Muppet -- a combination of the words "marionette" and "puppet."

How Muppets Are Made

New Muppets begin as a sketch by the Muppet art director, Ed Christie. Christie's drawings then get feedback from the writers, directors, and Muppeteers. The selections are narrowed down to one design, which Christie then turns into a finished drawing.

Once the drawing has been approved, the Muppet builders form the raw materials into a working puppet. Muppet builders are designers who have experience in sewing, sculpting, and pattern-making. Each Muppet is made of the same materials: foam rubber and adhesives. Muppets are decorated with faux furs, fabrics, eyes, noses, and other features such as horns, antennae, or embellishments, depending on their purpose. Engineers add any needed mechanisms, such as moving eyebrows or remote-controlled hands.

"Sesame Street" Around The Globe

From its inception, the strategy for "Sesame Street" has been to combine education with entertainment. By building a community of playful and curious Muppets, and adding a street scene that featured real children and adults, "Sesame Street" seems to have hit on the secret formula for taking children's television to a new level.

"Sesame Street" and its variations are now aired in approximately 140 different countries. Each of the show's international co-productions is carefully crafted to meet the specific needs of the local children, dealing with regional-specific issues. For example, the Israeli/Palestinian co-production "Rechov Sumsum/Shara's Simsim" is designed to teach children in both territories about mutual respect and tolerance. South Africa's "Takalani Sesame" features Kami, an HIV-positive Muppet.

While there are some familiar characters in the international versions, each show has its own unique Muppets that you won't find on the U.S. version. China has Xiao Mei Zi, a bright red female monster. Mexico's version of Big Bird is a huge green, yellow, and red parrot. Here's a look at some of the characters used in international productions of "Sesame Street":

Kami: A bright yellow HIV-positive Muppet on "Takalani Sesame" in South Africa who teaches AIDS awareness

Hu Hu Zhu: A blue opera-loving pig who teaches children about the arts on China's "Zhima Jie"

Haneen: A playful orange and pink monster with a vibrant personality who teaches tolerance on "Sesame Stories," shown in Israel, Palestine, and Jordan

Abelardo: Big Bird's cousin, who has green instead of yellow feathers and lives south of the border on "Plaza Sesamo"

Samsom: A big, brown, curious bear who loves to mambo on "Sesamstrasse" in Germany

Rumpel: Oscar the Grouch's green cousin on "Sesamstrasse." He lives in a barrel instead of a trashcan and spends his time with his best friend, Gustav, who is a caterpillar.

Zeliboba: This multicolored Muppet, who always wears a neck tie, was inspired by the tree spirits of Russian folklore. In Russia, Zeliboba and his buddies on "Ulitsa Sezam" encourage optimism, nutrition and health.

Louis: This French Canadian sea otter promotes Canadian culture and the French language on "Sesame Park"

Pino: Another one of Big Bird's cousins, Pino, is a blue bird who lives on "Sesamstraat" in the Netherlands. His catch phrase is "echt waar" ("really?"), and he helps children with socio-emotional development.

"Sesame Street" is indeed a hit around the world -- and so is Elmo. In the next section, we'll discuss "Elmo's World."

Fun Facts About the "Sesame Street" Muppets

So you think you know it all about the Muppets? Think again. Here's some interesting trivia:

Muppets always stay the same age.

Muppets do not know that they are being "handled" by a Muppeteer.

Muppets do not know they are on television. They only know they live and play on Sesame Street.

Kermit and Ernie are the only Muppets who were constructed with a built-in smile. All the other Muppets are built without expressions.

The "cookies" Cookie Monster eats are really rice cakes, not chocolate chip cookies. Chocolate, oil, and grease can damage the Muppet's hands and fur, so rice cakes are painted to look like cookies.

Most Muppeteers work from the ground, either crouching, sitting, or lying down. Often, they sit or lie on a rolling pad so that can move quickly and smoothly.

Rod Muppets, such as Bert, Grover, and Kermit, are handled by a single Muppeteer. His or her right hand goes in the Muppet's mouth, and the left hand works the rods that are attached to the Muppet's hands or feet.

Two-handed Muppets, such as Ernie and Cookie Monster, require two handlers. The Muppeteer who provides the character's voice also controls the mouth and the left hand. The other Muppeteer controls the right hand, which does the majority of the actions and handles any props.

Muppeteer Caroll Spinney wears Big Bird as a costume. Spinney works the mouth and eyes with his right hand and uses his left hand to control Big Bird's arms. Spinney has a microphone inside the costume and a monitor that allows him to see what he's doing.
